Samsung today announced Message Guard, a new security feature that protects Galaxy S23 phones (which go on sale today) against zero-click attacks delivered as images in messages. Samsung will update other Galaxy phones with the feature later this year. Message Guard intercepts incoming images before they reach Samsung Messages and Messages by Google, sandboxing and inspecting the files before they can carry out an attack. Only once Message Guard ensures a file "cannot infect the rest of your device" does it become available to the messaging app for viewing (processing an image for viewing is when this kind of attack can occur.) Samsung also committed to extending Message Guard to third party messaging apps "at a later date".
